<P>
|
|
Under Linux, the <EM>signal</EM> function is equivalent to using
|
|
<EM>sigaction</EM> with the <TT>SA_ONESHOT</TT> and <TT>SA_NOMASK</TT>
|
|
options; that is, it corresponds to the classic, unreliable
|
|
signal semantics as used under SVR4.
|
|
<P>
|
|
If you wish <EM>signal</EM> to use BSD semantics, most Linux systems
|
|
provide a BSD compatibility library which can be linked with. To use
|
|
this library, you could add the options
|
|
<PRE> -I/usr/include/bsd -lbsd</PRE>
|
|
to the compilation command line. When porting applications using
|
|
<EM>signal</EM>, pay close attention to what assumptions the program makes
|
|
about use of signal handlers, and modify the code (or compile with the
|
|
appropriate definitions) to get the right behavior.
